Keep the extent of your abilities unknown. The wise man does not allow his knowledge and
abilities to be sounded to the bottom, if he desires to be honored by all. He allows you to
know them but not to comprehend them. No one must know the extent of his abilities, lest he
be disappointed. No one ever has an opportunity of fathoming him entirely. For guesses and
doubts about the extent of his talents arouse more veneration than accurate knowledge of
them, be they ever so great.Baltasar Gracian
